H EAT-RADIATOR APPARATUS.

SPECIFICATION forming part of Letters Patent No. 395,818, dated January 8, 1889.

Application filed August 30, 1888. flerial No. 284,171. (No model.)

To all whom it may concern.-

Be it known. that I, ASA C. EDWARDS, of lVestfreld, in the county of Ilampd e11 and State of Massachusetts, have invented a new and Improved Heat-Rad iator Apparatus, of which the following is a full, clear, and exact description.

This invention relates to h cat-radiators, and has for its object to provide a heat-radiator apparatus by means of which the dampers of the radiator may be automatically opened and closed and the radiator tubes be cleansed from soot. e

Reference is to be had to the accompanying drawings, formin a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a view in elevation of a heatradiator apparatus constructed in accordance with this invention. Fig. 2 is a vertical section thereof, and Fig'. is a horizontal section on the line a: so of Fig. 1.

In the construction of this invention 1 indicates a heating-drum or section of pipe connected with or leading from a stove, furnace, or other heating apparatus. The drum 1 is provided in its lower portion with a spiral flange, 2, on a vertical. rod, 3, mounted on a horizontal lllftCkGlPfll'lll, "l', extendin from the side of the lower end of drum 1, by means of which spiral flange the heat ascending in drum 1 is deflected.

Above the spiral flange 2 are located a se ries of lnjirizontal. tubes, 5 5, extending across the drum '1, and having their ends open to the air surrounding the drum. The tubes are mounted in the drum so as to turn, and are provided with suitable operating crank-handles, 6. The tubes 5 are constructed with longitudinal flanges T, and are so arranged in the drum with relation to each other that the flanges 7 not only serve as dampers, but also actto scrape the exterior of the adjacent tube and clean it from soot. The tubes maybe rotated by the handles (5 to open and close the dampers formed by the flanges or to clean them of soot. One of the tubes 5 is also automatically rotated to regulate the damper by the following device: In the lower part of drum 1 is located a spiral rod, 8, secured at its lower end to the drum and connected at its upper endby a pin, 9, thereon extending through a curved slot, 10, in the side of the drum, with a lever-arm, 11, pivoted at one end 011 the outside of the drum and having its other forked end, 12, engaging a crankhandle, 6, of one of the tubes 5. The spiral rod 8 may be made of metal or a mineralsuch as iron, copper, brass, bismuth, (,QJC'. which will expand and contract, so as to efficiently act to operate the leverarm 11 and rotate the tube 5, connected therewith. By means of this construction the spiral rod 8 will be so affected by the heat as to expand and automatically regulate the damper. Upon the tire in the stove or furnace attaining a certain heat the spiral rod 8 will be lengthen ed sufficiently to raise the lever 11 and handle 6 and rotate the tube 5. The flanges 7 on tube 5 being vertical, upon the tube being rotated, as just described, the flanges 7 will be brought to a horizontal position with their edges against the wall of the drum and the adjacent tube, 5, thereby partly closing and regulating the draft.

In addition to the flanges 7 for scraping off the soot from the adjacent tubes, the lowest tube, 5, at the top of the spiral. flange 2 has adjacent to and parallel with it a. rod, 13, by means of which, on rotatii'ig the tube 5, the soot is scraped off therefrom. \V ith the tubes 5 arranged across'the heater the air surrounding the drum and passing througlii the tubes 5 will be thoroughly heated, the tubes 5 receiving the full effect of the hot air ascending in drum 1 by the radiation of heatover spiral flange 2 and between the irregularlyplaced tubes.

By means of a heat-radiator apparatus constructed in accordance with this invention the heat may be effectively radiated and automatically checked and the soot readily removed.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A lleat-radiator consisting of a heatingdrum having a series of rotary tubes with open ends, longitudinal flanges, and handles for operating the tubes, the latter being an tubes, substantially as shown and described.

2. A heat-radiator consisting of a heatingdruin having transverse rotary tubes with open ends, longitudinal flanges,an d operatin handles, the flanges on one side being equal to the distance between the tubes and the walls of the drum, the flanges thereby serving as soot-scrapers and dampers, substantially as shown and described.

3. A heat-radiator consisting of a heatingdrum having transverse rotary tubes with open ends, soot-scraper and damper-flanges and operating-handles, and a vertical spiral flange located beneath the tubes, substantially as shown and described.

4. A heat-radiator consisting of a heatingdrum having transverse rotary tubes with open ends, soot-scraper and damper-flanges and operating-handles, and a spiral expansible rod having one end connected by a lever to one of the tube-operatin g handles, substantially as shown and described.

5. In a heat-radiator, a transverse rotary tube with operating-handle, and a soot-scraper rod adjacent to and parallel with the rotary tube, substantially as shown and described.

6. A heat radiator consisting of drum 1, having the vertical spiral flange 2 mounted in its lower end, the transverse rotary tubes 5, located above the spiral flange 2 with open ends, soot-scraper and damper-flanges 7 and operatin g-handles 6, and the expansible spiral. rod 8, secured in the lower part of drn1n,alever pivoted on the outside of the drum and pivotally connected to the upper end of rod 8,

' and having a forked end, 12, engaging one of the leXer-handles ll, substantially as shown and described.
